Program to alert when elapsed CPU percentage becomes too high

Introduction
Monitoring CPU usage on IBM i systems is critical for maintaining optimal performance and resource allocation. High CPU usage can lead to system slowdowns and affect application responsiveness.
Program Overview
This article outlines a program designed to alert administrators when the elapsed CPU percentage exceeds predefined thresholds. The program utilizes system APIs to gather real-time CPU usage data and triggers alerts based on specified criteria.

• API Utilization: The program leverages IBM i system APIs to retrieve CPU usage metrics efficiently.
• Threshold Configuration: Administrators can set customizable thresholds for CPU usage, allowing for tailored monitoring based on specific workload requirements.
• Alert Mechanism: The program implements an alert mechanism that notifies system administrators via email or system messages when CPU usage surpasses the defined limits.
• Logging and Reporting: The program logs CPU usage data and alerts, providing a historical record for analysis and troubleshooting.

Conclusion
Implementing this program enhances system administration capabilities on IBM i platforms. By proactively monitoring CPU usage and receiving timely alerts, administrators can take corrective actions to prevent performance degradation and ensure system reliability.
